A lawsuit against South West Water (SWW) over sewage pollution in coastal areas is being expanded.

Law firm Leigh Day said it was opening the claim to include people from the Devon towns of Dawlish, Sidmouth and Teignmouth, as well as Newquay and Penzance in Cornwall. It was previously limited to people living in Exmouth, Budleigh Salterton and Lympstone.

Lawyers argued SWW’s failings were “wide and entrenched in many coastal towns across the Devon and Cornwall region”.
